Answer:
<h2>5'-UCAAUGC-3'</h2>
Explanation:
According to base pairing rule of DNA and RNA, A is always pairs with T ( in case of DNA) or with U ( in case of RNA) with two hydrogen bonds(A=T), and C is always pairs with G in both DNA and RNA with three hydrogen bonds ( C≡G).
As given here, one segment of RNA molecule containing sequence 5'-GCAUUGA-3', so as the rule, G always binds with C and so on, so the sequence of the binding segment would be 3'-CGUAACU-5'. it can be written as 5'-UCAAUGC-3'
A certain drug is made from only two ingredients: compound A and compound B. There are 5 milliliters of compound A used for every 4 milliliters of compound B. If a chemist uses 255 milliliters of compound A, how many milliliters of the drug will be made?
----------------------------------
4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.
---
Solve for "x":
If amount of compound A is 4x = 255
x = 255/4
------------------------------
Then amount of compound B is 5x = 5(255/4) = 318.75 ml

Asteroid impact
Volcanic eruptions
Explanation:
Asteroid impact and volcanic eruptions are two common events that could lead to a mass extinction.
A mass extinction is an abrupt decrease in life on earth due some catastrophic event.
- The collision of a large bolide on the surface of the earth is a catastrophe in itself.
- The collision and its aftermath have destructive consequences on life.
- The force of the collision can reverberate in form of vibration throughout the earth.
- It can cause heating of the earth surface.
- Volcanic eruptions can become global phenomenon that upsets the earth balance.

Answer:
Zooplankton - Animals (mostly microscopic) which drift freely in the water column.
Explanation: Zooplankton, small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
